BACKGROUND OF THE INVENTION

The present invention relates to benzazepine derivatives, pharmaceuticalcompositions comprising such benzazepine derivatives, and the use ofsuch benzazepine derivatives for therapeutic purposes. The benzazepinederivatives are GlyT1 inhibitors.

Dysfunction of glutamatergic pathways has been implicated in a number ofdisease states in the human central nervous system (CNS) including butnot limited to schizophrenia, cognitive deficits, dementia, Parkinsondisease, Alzheimer disease and bipolar disorder. A large number ofstudies in animal models lend support to the NMDA hypofunctionhypothesis of schizophrenia.

NMDA receptor function can be modulated by altering the availability ofthe co-agonist glycine. This approach has the critical advantage ofmaintaining activity-dependent activation of the NMDA receptor becausean increase in the synaptic concentration of glycine will not produce anactivation of NMDA receptors in the absence of glutamate. Since synapticglutamate levels are tightly maintained by high affinity transportmechanisms, an increased activation of the glycine site will onlyenhance the NMDA component of activated synapses.

Two specific glycine transporters, GlyT1 and GlyT2 have been identifiedand shown to belong to the Na/Cl-dependent family of neurotransmittertransporters which includes taurine, gamma-aminobutyric acid (GABA),proline, monoamines and orphan transporters. GlyT1 and GlyT2 have beenisolated from different species and shown to have only 50% identity atthe amino acid level. They also have a different pattern of expressionin mammalian central nervous system, with GlyT2 being expressed inspinal cord, brainstem and cerebellum and GlyT1 present in these regionsas well as forebrain areas such as cortex, hippocampus, septum andthalamus. At the cellular level, GlyT2 has been reported to be expressedby glycinergic nerve endings in rat spinal cord whereas GlyT1 appears tobe preferentially expressed by glial cells. These expression studieshave led to the suggestion that GlyT2 is predominantly responsible forglycine uptake at glycinergic synapses whereas GlyT1 is involved inmonitoring glycine concentration in the vicinity of NMDA receptorexpressing synapses. Recent functional studies in rat have shown thatblockade of GlyT1 with the potent inhibitor(N-[3-(4′-fluorophenyl)-3-(4′-phenylphenoxy)propyl])-sarcosine (NFPS)potentiates NMDA receptor activity and NMDA receptor-dependent long-termpotentiation in rat.

Molecular cloning has further revealed the existence of three variantsof GlyT1, termed GlyT-1a, GlyT-1b and GlyT-1c, each of which displays aunique distribution in the brain and peripheral tissues. The variantsarise by differential splicing and exon usage, and differ in theirN-terminal regions.

The physiological effects of GlyT1 in forebrain regions together withclinical reports showing the beneficial effects of GlyT1 inhibitorsarcosine in improving symptoms in schizophrenia patients suggest thatselective GlyT1 inhibitors represent a new class of antipsychotic drugs.

Glycine transporter inhibitors are already known in the art, forexample:

DETAILED DESCRIPTION OF THE INVENTION

Provided that the benzazepine derivatives of the formula (I) of a givenconstitution may exist in different spatial arrangements, for example ifthey possess one or more centers of asymmetry, polysubstituted rings ordouble bonds, or as different tautomers, it is also possible to useenantiomeric mixtures, in particular racemates, diastereomeric mixturesand tautomeric mixtures, preferably, however, the respective essentiallypure enantiomers, diastereomers and tautomers of the compounds offormula (I) and/or of their salts.

According to one embodiment, an enantiomer of the benzazepinederivatives of the present invention has the following formula:

wherein R, R², A³, R³, R⁴, X², X³, R⁵ are as defined herein.

According to another embodiment, an enantiomer of the benzazepinederivatives of the present invention has the following formula:

wherein R, R², A³, R³, R⁴, X², X³, R⁵ are as defined herein.

The physiologically tolerated salts of the benzazepine derivatives ofthe formula (I) are especially acid addition salts with physiologicallytolerated acids. Examples of suitable physiologically tolerated organicand inorganic acids are hydrochloric acid, hydrobromic acid, phosphoricacid, sulfuric acid, C₁-C₄-alkylsulfonic acids, such as methanesulfonicacid, cycloaliphatic sulfonic acids, such as S-(+)-10-camphor sulfonicacid, aromatic sulfonic acids, such as benzenesulfonic acid andtoluenesulfonic acid, di- and tricarboxylic acids and hydroxycarboxylicacids having 2 to 10 carbon atoms, such as oxalic acid, malonic acid,maleic acid, fumaric acid, lactic acid, tartaric acid, citric acid,glycolic acid, adipic acid and benzoic acid. Other utilizable acids aredescribed, e.g., in Fortschritte der Arzneimittelforschung [Advances indrug research], Volume 10, pages 224 ff., Birkhauser Verlag, Basel andStuttgart, 1966. The physiologically tolerated salts of the benzazepinederivatives also include salts of a physiologically tolerated anion withan benzazepine derivatives wherein one or more than one nitrogen atom isquaternized, e.g. with an alkyl residue (e.g. methyl or ethyl).

The present invention moreover relates to compounds of formula (I) asdefined herein, wherein at least one of the atoms has been replaced byits stable, non-radioactive isotope (e.g., hydrogen by deuterium, ¹²C by¹³C, ¹⁴N by ¹⁵N_(,) ¹⁶O by ¹⁸O) and preferably wherein at least onehydrogen atom has been replaced by a deuterium atom.

Of course, such compounds contain more of the respective isotope thanthis naturally occurs and thus is anyway present in the compounds (I).

Stable isotopes (e.g., deuterium, ¹³C, ¹⁵N, ¹⁸O) are nonradioactiveisotopes which contain one or more additional neutron than the normallyabundant isotope of the respective atom. Deuterated compounds have beenused in pharmaceutical research to investigate the in vivo metabolicfate of the compounds by evaluation of the mechanism of action andmetabolic pathway of the non-deuterated parent compound (Blake et al. J.Pharm. Sci. 64, 3, 367-391 (1975)). Such metabolic studies are importantin the design of safe, effective therapeutic drugs, either because thein vivo active compound administered to the patient or because themetabolites produced from the parent compound prove to be toxic orcarcinogenic (Foster et al., Advances in Drug Research Vol. 14, pp.2-36, Academic press, London, 1985; Kato et al., J. Labelled Comp.Radiopharmaceut., 36(10):927-932 (1995); Kushner et al., Can. J.Physiol. Pharmacol., 77, 79-88 (1999).

Incorporation of a heavy atom particularly substitution of deuterium forhydrogen, can give rise to an isotope effect that could alter thepharmacokinetics of the drug. This effect is usually insignificant ifthe label is placed at a metabolically inert position of the molecule.

Stable isotope labeling of a drug can alter its physico-chemicalproperties such as pKa and lipid solubility. These changes may influencethe fate of the drug at different steps along its passage through thebody. Absorption, distribution, metabolism or excretion can be changed.Absorption and distribution are processes that depend primarily on themolecular size and the lipophilicity of the substance. These effects andalterations can affect the pharmacodynamic response of the drug moleculeif the isotopic substitution affects a region involved in aligand-receptor interaction.

Drug metabolism can give rise to large isotopic effect if the breakingof a chemical bond to a deuterium atom is the rate limiting step in theprocess. While some of the physical properties of a stableisotope-labeled molecule are different from those of the unlabeled one,the chemical and biological properties are the same, with one importantexception: because of the increased mass of the heavy isotope, any bondinvolving the heavy isotope and another atom will be stronger than thesame bond between the light isotope and that atom. In any reaction inwhich the breaking of this bond is the rate limiting step, the reactionwill proceed slower for the molecule with the heavy isotope due to“kinetic isotope effect”. A reaction involving breaking a C-D bond canbe up to 700 percent slower than a similar reaction involving breaking aC—H bond. If the C-D bond is not involved in any of the steps leading tothe metabolite, there may not be any effect to alter the behavior of thedrug. If a deuterium is placed at a site involved in the metabolism of adrug, an isotope effect will be observed only if breaking of the C-Dbond is the rate limiting step. There is evidence to suggest thatwhenever cleavage of an aliphatic C—H bond occurs, usually by oxidationcatalyzed by a mixed-function oxidase, replacement of the hydrogen bydeuterium will lead to observable isotope effect. It is also importantto understand that the incorporation of deuterium at the site ofmetabolism slows its rate to the point where another metabolite producedby attack at a carbon atom not substituted by deuterium becomes themajor pathway a process called “metabolic switching”.

Deuterium tracers, such as deuterium-labeled drugs and doses, in somecases repeatedly, of thousands of milligrams of deuterated water, arealso used in healthy humans of all ages, including neonates and pregnantwomen, without reported incident (e.g. Pons G and Rey E, Pediatrics 1999104: 633; Coward W A et al., Lancet 1979 7: 13; Schwarcz H P, Control.Clin. Trials 1984 5(4 Suppl): 573; Rodewald L E et al., J. Pediatr. 1989114: 885; Butte N F et al. Br. J. Nutr. 1991 65: 3; MacLennan A H et al.Am. J. Obstet. Gynecol. 1981 139: 948). Thus, it is clear that anydeuterium released, for instance, during the metabolism of compounds ofthis invention poses no health risk.

The weight percentage of hydrogen in a mammal (approximately 9%) andnatural abundance of deuterium (approximately 0.015%) indicates that a70 kg human normally contains nearly a gram of deuterium. Furthermore,replacement of up to about 15% of normal hydrogen with deuterium hasbeen effected and maintained for a period of days to weeks in mammals,including rodents and dogs, with minimal observed adverse effects(Czajka D M and Finkel A J, Ann. N.Y. Acad. Sci. 1960 84: 770; Thomson JF, Ann. New York Acad. Sci. 1960 84: 736; Czakja D M et al., Am. J.Physiol. 1961 201: 357). Higher deuterium concentrations, usually inexcess of 20%, can be toxic in animals. However, acute replacement of ashigh as 15%-23% of the hydrogen in humans' fluids with deuterium wasfound not to cause toxicity (Blagojevic N et al. in “Dosimetry &Treatment Planning for Neutron Capture Therapy”, Zamenhof R, Solares Gand Harling 0 Eds. 1994. Advanced Medical Publishing, Madison Wis. pp.125-134; Diabetes Metab. 23: 251 (1997)).

Increasing the amount of deuterium present in a compound above itsnatural abundance is called enrichment or deuterium-enrichment. Examplesof the amount of enrichment include from about 0.5, 1, 2, 3, 4, 5, 6, 7,8, 9, 10, 12, 16, 21, 25, 29, 33, 37, 42, 46, 50, 54, 58, 63, 67, 71,75, 79, 84, 88, 92, 96, to about 100 mol %.

The hydrogens present on a particular organic compound have differentcapacities for exchange with deuterium. Certain hydrogen atoms areeasily exchangeable under physiological conditions and, if replaced bydeuterium atoms, it is expected that they will readily exchange forprotons after administration to a patient. Certain hydrogen atoms may beexchanged for deuterium atoms by the action of a deuteric acid such asD₂SO₄/D₂O. Alternatively, deuterium atoms may be incorporated in variouscombinations during the synthesis of compounds of the invention. Certainhydrogen atoms are not easily exchangeable for deuterium atoms. However,deuterium atoms at the remaining positions may be incorporated by theuse of deuterated starting materials or intermediates during theconstruction of compounds of the invention.

Deuterated and deuterium-enriched compounds of the invention can beprepared by using known methods described in the literature. Suchmethods can be carried out utilizing corresponding deuterated andoptionally, other isotope-containing reagents and/or intermediates tosynthesize the compounds delineated herein, or invoking standardsynthetic protocols known in the art for introducing isotopic atoms to achemical structure.

Further particular compounds of the present invention are the individualbenzazepine derivatives of the formula (Id) as listed in tables 1 to 12and physiologically tolerated salts thereof wherein the radicalR¹—S(O)₂—Y-A²-X¹— is replaced by the radical —CN.

Further particular compounds of the present invention are thebenzazepine derivatives disclosed in preparation examples andphysiologically tolerated salts thereof. These include for eachpreparation example the exemplified compound as well as thecorresponding free base and any other physiologically tolerated salts ofthe free base (if the exemplified compound is a salt), or anyphysiologically tolerated salt of the free base (if the exemplifiedcompound is a free base). These further include enantiomers,diastereomers, tautomers and any other isomeric forms of said compounds,be they explicitly or implicitly disclosed.

The compounds of the formula (I) can be prepared by analogy to methodswhich are well known in the art. Suitable methods for the preparation ofcompounds of formula (I) are outlined in the following schemes.

The process depicted in scheme 1 is useful for obtaining benzazepineprecursors of the general formula 3, wherein X¹ is —O— or —S— and A³ isoptionally substituted alkylene (e.g. —CH₂—).

As shown in scheme 1, the compound of general formula 1 readilyundergoes enamine alkylation to give the enamine 2 and after subsequenthydrolysis the compound of general formula 3.

In scheme 1, the variables X², X³, R⁵ are as defined herein, and L¹represents an alkyl substituent (e.g. Me, Et, Bn).

The process depicted in scheme 1 is also useful for obtainingbenzazepines, wherein X¹ is optionally substituted alkylene. In thiscase, L¹ is a group that represents, or can be converted into, thedesired side chain R¹—W-A¹-Q-Y-A²-.

Alternatively, compounds of formula 3 can be prepared as described inscheme 2.

As shown in scheme 2, the compound of general formula 4 readilyundergoes alkylation to give the compound of general formula 5.Conversion to the acid chloride and subsequent ring closure withethylene in the presence of a Lewis acid (e.g. AlCl₃) affords compound 3(e.g. J. Het. Chem., 23 (2), 343, 1986 and Bioorg. Med. Chem. Let, 17(22), 6160, 2007).

In scheme 2, the variables X¹, X², X³, R⁵ are as defined herein and L¹and L² are suitable protecting groups (e.g. L¹=Me, Et, Bn). Compounds 3can be further converted to compounds of the general formula (I).

The process depicted in scheme 3 is useful for obtaining bezazepines,wherein X¹ is —O— or —S—, A³ is optionally substituted alkylene (e.g.—CH₂—), Y is —NR⁹—, and Q is —S(O)₂.

Compounds of the general formula 3 readily undergo condensationreactions to the corresponding mixtures of E- and Z-oxims 4. The oximscan be transferred into the tosylates, which subsequently undergo aBeckmann rearrangement to give a mixture of lactames of the generalformula 5 and 6 (e.g. Org. Lett. 2, 2373, 2000). Alternatively, theBeckmann rearrangement can be carried out under acidic conditions toconvert the oxims 4 directly to the lactames 5 and 6. Lactames 5 and 6can be separated (e.g. flash chromatography). Lactames 5 can beconverted to the amines of the general formula 7 using LiAlH₄ or otherwell known reducing agents (BH₃Me₂S). Protection of the amino group witha suitable protecting group (e.g. L²=COOEt) leads to compounds of thegeneral formula 8.

In scheme 3, the variables R¹, W, A¹, R², R³, R⁴, X², X³, R⁵, R⁹, A² areas defined herein and L¹ and L² are suitable protecting groups (e.g.L¹=Me, Et, Bn, or tBuMe₂Si; L²=COOtBu or COOEt).

The process depicted in scheme 4 is useful for obtaining benzazepines,wherein X¹ is methylene, A² is a bond, Y is —NR⁹—, and Q is —S(O)₂.

Instead of the triflate 18, the corresponding bromide, iodide, ornonaflate can be used to prepare compound 19.

In scheme 4, the variables R¹, W, A¹, R², R³, R⁴, X², X³, R⁵, R⁹ are asdefined herein, and L¹ and L² are a suitable protecting group (e.g.L¹=Me, Et, Bn, or tBuMe₂Si; L²=COO^(t)Bu or COOEt).

The process depicted in scheme 5 is useful for obtaining benzazepines,wherein X¹ is optionally substituted alkylene, A² is optionallysubstituted alkylene or a bond, Y is —NR⁹—, and Q is —S(O)₂.

Instead of the trifluoroborate 24, the corresponding9-borabicyclo[3.3.1]non-9-yl derivative can be used to prepare compound25.

In scheme 5, the variables R¹, W, A¹, R², R³, R⁴, X², X³, R⁵, R⁹ are asdefined herein, and L² is a suitable protecting group (e.g. L²=COO^(t)Buor COOEt).

The process depicted in scheme 6 is useful for obtaining benzazepines,wherein X is —NR¹¹—, A² is optionally substituted alkylene, Y is —NR⁹—,and Q is —S(O)₂.

In scheme 6, the variables R¹, W, A¹, R¹¹, R², R³, R⁴, X², X³, R⁵, R⁹are as defined herein, and L² and L⁴ are a suitable protecting group(e.g. L², L⁴=COO^(t)Bu or COOEt).

The process depicted in scheme 7 is useful for obtaining benzoxazepineprecursors of the general formula 39, wherein X′ is —O— or —S— and A³ is—O—.

As shown in scheme 7, the compound of general formula 33 readilyundergoes alkylation to give the compound of general formula 34.Deprotection leads to compounds of the general formula 35, which areconverted via well known amide coupling reactions to the correspondingcompounds of general formula 36 (e.g. EDC, DMAP). Amides of the generalformula 36 undergo cyclization to imines of the formula 37 underVilsmeier reaction conditions (e.g. POCl₃, SOCl₂, oxalyl chloride; seeChem. Ind. 1973, 870, Indian J. Chem., Sect. B (37B), 1998, 965, andAdvances in Organic Chemistry (9), Pt. 1, 1976, 225). Re-duction ofimins of the general formula 37 (e.g. with NaBH₄) readily gives thecorresponding amines of general formula 38. Protection of the free aminewith a suitable protecting group (e.g. L²=COO^(t)Bu) yields compounds ofthe general formula 39. Introduction of the various side chains isperformed as already described for the benzazepine derivatives inschemes 4 to 6.

In scheme 7, the variables R², R³, R⁴, X², X³, R⁵ are as defined herein,L represents an alkyl substituent (e.g. Me, Et, Bn) and L² is a suitableprotecting group (e.g. L²=COO^(t)Bu or COOEt).

The process depicted in scheme 7 is also useful for obtainingbenzazepines derivatives of formula (I), wherein A³ is —S—, or NR¹⁶.

The acid addition salts of the benzazepine derivatives of formula (I)are prepared in a customary manner by mixing the free base with acorresponding acid, optionally in solution in an organic solvent, forexample a lower alcohol, such as methanol, ethanol or propanol, anether, such as methyl tert-butyl ether or diisopropyl ether, a ketone,such as acetone or methyl ethyl ketone, or an ester, such as ethylacetate.

The benzazepines derivatives of formula (II):

wherein L is an amino-protecting group, Y is NR⁹, and A², X¹, R², A³,R³, R⁴, X², X³, R⁵ are defined as herein are useful as intermediates inthe preparation of GlyT1 inhibitors, in particular those of formula (I).

Suitable amino-protecting groups are well known in the art such as thosedescribed in Protective Groups in Organic Chemistry, ed. J. F. W.McOmie, Plenum Press, 1973; and T. W. Greene & P. G. M. Wuts, ProtectiveGroups in Organic Synthesis, John Wiley & Sons, 1991.

According to a particular embodiment, L is optionally substitutedalkylcarbonyl (e.g., tertbutylcarbonyl), optionally substitutedarylcarbonyl, optionally substituted arylalkycarbonyl (e.g.,benzylcarbonyl), optionally substituted alkoxycarbonyl (e.g.,methoxycarbonyl or tert-butyloxycarbonyl), optionally substitutedaryloxycarbonyl (e.g. phenoxycarbonyl) or optionally substitutedarylalkoxycarbonyl.

The compounds of the formula (I) are capable of inhibiting the activityof glycine transporter, in particular glycine transporter 1 (GlyT1).

The utility of the compounds in accordance with the present invention asinhibiting the glycine transporter activity, in particular GlyT1activity, may be demonstrated by methodology known in the art. Forinstance, human GlyT1c expressing recombinant hGlyT1c_(—)5_CHO cells canbe used for measuring glycine uptake and its inhibition (IC₅₀) by acompound of formula (I).

Amongst the compounds of the formula (I) those are preferred whichachieve effective inhibition at low concentrations. In particular,compounds of the formula (I) are preferred which inhibit glycinetransporter 1 (GlyT1) at a level of IC₅₀<1 μMol, more preferably at alevel of IC₅₀<0.5 μMol, particularly preferably at a level of IC₅₀<0.2μMol and most preferably at a level of IC₅₀<0.1 μMol.

The compounds of formula (I) display good to moderate metabolicstability.

The metabolic stability of a compound can be measured for example byincubating a solution of this compound with liver microsomes fromparticular species (for example rat, dog or human) and determining thehalf-life of the compound under these conditions (RS Obach, Curr OpinDrug Discov Devel. 2001, 4, 36-44). It is possible in this connection toconclude from an observed longer half-life that the metabolic stabilityof the compound is improved. The stability in the presence of humanliver microsomes is of particular interest because it makes it possibleto predict the metabolic degradation of the compound in the human liver.Compounds with increased metabolic stability (measured in the livermicrosome test) are therefore probably also degraded more slowly in theliver. The slower metabolic degradation in the liver may lead to higherand/or longer-lasting concentrations (active levels) of the compound inthe body, so that the elimination half-life of the compounds of theinvention is increased. Increased and/or longer-lasting active levelsmay lead to a better activity of the compound in therapeutic treatment.In addition, an improved metabolic stability may lead to an increasedbioavailability after oral administration, because the compound issubject, after absorption in the intestine, to less metabolicdegradation in the liver (so-called first pass effect). An increasedoral bioavailability may, owing to an increased concentration (activelevel) of the compound, lead to a better activity of the compound afteroral administration.

Amongst the compounds of the formula (I) those are particularlypreferred which display good to moderate metabolic stability towardshuman liver microsomes. In particular, compounds of the formula (I) arepreferred which display a microsomal clearance at a level of mCl <1000μl/min/mg, more preferably at a level of mCl <500 μl/min/mg,particularly preferably at a level of mCl <100 μl/min/mg and mostpreferably at a level of mCl <50 μl/min/mg.

The compounds of the formula (I) according to the present invention arethus useful as pharmaceuticals.

The present invention therefore also relates to pharmaceuticalcompositions which comprise an inert carrier and a compound of theformula (I).

The present invention also relates to the use of the compounds of theformula (I) in the manufacture of a medicament for inhibiting theglycine transporter GlyT1, and to corresponding methods of inhibitingthe glycine transporter GlyT1.

The NMDA receptor is central to a wide range of CNS processes, and itsrole in a variety of diseases in humans or other species has beendescribed. GlyT1 inhibitors slow the removal of glycine from thesynapse, causing the level of synaptic glycine to rise. This in turnincreases the occupancy of the glycine binding site on the NMDAreceptor, which increases activation of the NMDA receptor followingglutamate release from the presynaptic terminal. Glycine transportinhibitors and in particular inhibitors of the glycine transporter GlyT1are thus known to be useful in treating a variety of neurologic andpsychiatric disorders. Further, glycine A receptors play a role in avariety of diseases in humans or other species. Increasing extracellularglycine concentrations by inhibiting glycine trans-port may enhance theactivity of glycine A receptors. Glycine transport inhibitors and inparticular inhibitors of the glycine transporter GlyT1 are thus usefulin treating a variety of neurologic and psychiatric disorders.

The present invention thus further relates to the use of the compoundsof the formula (I) for the manufacture of a medicament for treating aneurologic or psychiatric disorder, and to corresponding methods oftreating said disorders.

According to a particular embodiment, the disorder is associated withglycinergic or glutamatergic neurotransmission dysfunction.

According to a further particular embodiment, the disorder is pain, inparticular chronic pain and especially neuropathic pain.

Pain can be classified as acute and chronic pain. Acute pain and chronicpain differ in their etiology, pathophysiology, diagnosis and treatment.

Acute pain, which occurs following tissue injury, is self-limiting,serves as an alert to ongoing tissue damage and following tissue repairit will usually subside. There are minimal psychological symptomsassociated with acute pain apart from mild anxiety. Acute pain isnociceptive in nature and occurs following chemical, mechanical andthermal stimulation of A-delta and C-polymodal pain receptors.

Chronic pain, on the other hand, serves no protective biologicalfunction. Rather than being the symptom of tissue damage it is a diseasein its own right. Chronic pain is unrelenting and not self-limiting andcan persist for years, perhaps decades after the initial injury. Chronicpain can be refractory to multiple treatment regimes. Psychologicalsymptoms associated with chronic pain include chronic anxiety, fear,depression, sleeplessness and impairment of social interaction. Chronicnon-malignant pain is predominantly neuropathic in nature and involvesdamage to either the peripheral or central nervous systems.

Acute pain and chronic pain are caused by different neuro-physiologicalprocesses and therefore tend to respond to different types oftreatments. Acute pain can be somatic or visceral in nature. Somaticpain tends to be a well localised, constant pain and is described assharp, aching, throbbing or gnawing. Visceral pain, on the other hand,tends to be vague in distribution, paroxysmal in nature and is usuallydescribed as deep, aching, squeezing or colicky in nature. Examples ofacute pain include post-operative pain, pain associated with trauma andthe pain of arthritis. Acute pain usually responds to treatment withopioids or non-steroidal anti-inflammatory drugs.

Chronic pain, in contrast to acute pain, is described as burning,electric, tingling and shooting in nature. It can be continuous orparoxysmal in presentation. The hallmarks of chronic pain are chronicallodynia and hyperalgesia. Allodynia is pain resulting from a stimulusthat normally does not ellicit a painful response, such as a lighttouch. Hyperalgesia is an increased sensitivity to normally painfulstimuli. Primary hyperalgesia occurs immediately within the area of theinjury. Secondary hyperalgesia occurs in the undamaged area surroundingthe injury. Examples of chronic pain include complex regional painsyndrome, pain arising from peripheral neuropathies, post-operativepain, chronic fatigue syndrome pain, tension-type headache, pain arisingfrom mechanical nerve injury and severe pain associated with diseasessuch as cancer, metabolic disease, neurotropic viral disease,neurotoxicity, inflammation, multiple sclerosis or any pain arising as aconsequence of or associated with stress or depressive illness.

Although opioids are cheap and effective, serious and potentiallylife-threatening side effects occur with their use, most notablyrespiratory depression and muscle rigidity. In addition the doses ofopioids which can be administered are limited by nausea, emesis,constipation, pruritis and urinary retention, often resulting inpatients electing to receive suboptimal pain control rather than sufferthese distressing side-effects. Furthermore, these side-effects oftenresult in patients requiring extended hospitalisation. Opioids arehighly addictive and are scheduled drugs in many territories.

The compounds of formula (I) are particularly useful in the treatment ofschizophrenia, bipolar disorder, depression including unipolardepression, seasonal depression and post-partum depression, premenstrualsyndrome (PMS) and premenstrual dysphoric disorder (PDD), learningdisorders, pervasive developmental disorder including autistic disorder,attention deficit disorders including Attention-Deficit/HyperactivityDisorder, tic disorders including Tourette's disorder, anxiety disordersincluding phobia and post traumatic stress disorder, cognitive disordersassociated with dementia, AIDS dementia, Alzheimer's, Parkinson's,Huntington's disease, spasticity, myoclonus, muscle spasm, tinnitus andhearing impairment and loss are of particular importance.

Particular cognitive disorders are dementia, delirium, amnesticdisorders and cognitive impartment including age-related cognitivedecline.

Particular anxiety disorders are generalized anxiety disorder,obsessive-compulsive disorder and panic attack.

Particular schizophrenia or psychosis pathologies are paranoid,disorganized, catatonic or undifferentiated schizophrenia andsubstance-induced psychotic disorder.

Within the context of the treatment, the use according to the inventionof the compounds of the formula (I) involves a method. In this method,an effective quantity of one or more compounds or the formula (I), as arule formulated in accordance with pharmaceutical and veterinarypractice, is administered to the individual to be treated, preferably amammal, in particular a human being. Whether such a treatment isindicated, and in which form it is to take place, depends on theindividual case and is subject to medical assessment (diagnosis) whichtakes into consideration signs, symptoms and/or malfunctions which arepresent, the risks of developing particular signs, symptoms and/ormalfunctions, and other factors.

As a rule, the treatment is effected by means of single or repeateddaily administration, where appropriate together, or alternating, withother drugs or drug-containing preparations.

The invention also relates to the manufacture of pharmaceuticalcompositions for treating an individual, preferably a mammal, inparticular a human being. Thus, the compounds of the formula (I) arecustomarily administered in the form of pharmaceutical compositionswhich comprise an inert carrier (e.g. a pharmaceutically acceptableexcipient) together with at least one compound according to theinvention and, where appropriate, other drugs. These compositions can,for example, be administered orally, rectally, transdermally,subcutaneously, intravenously, intramuscularly or intranasally.

Examples of suitable pharmaceutical formulations are solid medicinalforms, such as powders, granules, tablets, in particular film tablets,lozenges, sachets, cachets, sugarcoated tablets, capsules, such as hardgelatin capsules and soft gelatin capsules, suppositories or vaginalmedicinal forms, semisolid medicinal forms, such as ointments, creams,hydrogels, pastes or plasters, and also liquid medicinal forms, such assolutions, emulsions, in particular oil-in-water emulsions, suspensions,for example lotions, injection preparations and infusion preparations,and eyedrops and eardrops. Implanted release devices can also be usedfor administering inhibitors according to the invention. In addition, itis also possible to use liposomes or microspheres.

When producing the compositions, the compounds according to theinvention are optionally mixed or diluted with one or more carriers(excipients). Carriers (excipients) can be solid, semisolid or liquidmaterials which serve as vehicles, carriers or medium for the activecompound.

Suitable carriers (excipients) are listed in the specialist medicinalmonographs. In addition, the formulations can comprise pharmaceuticallyacceptable auxiliary substances, such as wetting agents; emulsifying andsuspending agents; preservatives; antioxidants; antiirritants; chelatingagents; coating auxiliaries; emulsion stabilizers; film formers; gelformers; odor masking agents; taste corrigents; resin; hydrocolloids;solvents; solubilizers; neutralizing agents; diffusion accelerators;pigments; quaternary ammonium compounds; refatting and overfattingagents; raw materials for ointments, creams or oils; siliconederivatives; spreading auxiliaries; stabilizers; sterilants; suppositorybases; tablet auxiliaries, such as binders, fillers, glidants,disintegrants or coatings; propellants; drying agents; opacifiers;thickeners; waxes; plasticizers and white mineral oils. A formulation inthis regard is based on specialist knowledge as described, for example,in Fiedler, H. P., Lexikon der Hilfsstoffe für Pharmazie, Kosmetik andangrenzende Gebiete [Encyclopedia of auxiliary substances for pharmacy,cosmetics and related fields], 4^(th) edition, Aulendorf:ECVEditio-Cantor-Verlag, 1996.

The combination therapies of the invention may be administeredadjunctively. By adjunctive administration is meant the coterminous oroverlapping administration of each of the components in the form ofseparate pharmaceutical compositions or devices. This regime oftherapeutic administration of two or more therapeutic agents is referredto generally by those skilled in the art and herein as adjunctivetherapeutic administration; it is also known as add-on therapeuticadministration. Any and all treatment regimes in which a patientreceives separate but coterminous or overlapping therapeuticadministration of the compounds of formula (I) and at least one furthertherapeutic agent are within the scope of the current invention. In oneembodiment of adjunctive therapeutic administration as described herein,a patient is typically stabilized on a therapeutic administration of oneor more of the components for a period of time and then receivesadministration of another component.

Biological Testing

1. [³H]-Glycine Uptake into Recombinant CHO Cells Expressing HumanGlyT1:

Human GlyT1c expressing recombinant hGlyT1c_(—)5_CHO cells were platedat 20,000 cells per well in 96 well Cytostar-T scintillation microplates(Amersham Biosciences) and cultured to sub-confluency for 24 h. Forglycine uptake assays the culture medium was aspirated and the cellswere washed once with 100 μl HBSS (Gibco BRL, #14025-050) with 5 mML-Alanine (Merck #1007). 80 μl HBSS buffer were added, followed by 10 μlinhibitor or vehicle (10% DMSO) and 10 μl [³H]-glycine (TRK71, AmershamBiosciences) to a final concentration of 200 nM for initiation ofglycine uptake. The plates were placed in a Wallac Microbeta(PerkinElmer) and continuously counted by solid phase scintillationspectrometry during up to 3 hours. Nonspecific uptake was determined inthe presence of 10 μM Org24598. IC₅₀ calculations were made byfour-parametric logistic nonlinear regression analysis (GraphPad Prism)using determinations within the range of linear increase of [³H]-glycineincorporation between 60 and 120 min.

2. Radioligand Binding Assays Using Recombinant CHO Cell MembranesExpressing Human GlyT1:

Radioligand binding to human GlyT1c transporter-expressing membranes wasdetermined as described in Mezler et al., Molecular Pharmacology74:1705-1715, 2008.

3. Metabolic Stability

Metabolic stability was determined as follows:

0.5 μM test substance was preincubated together with human livermicrosomes (0.25 mg of microsomal protein/ml) in 0.05 M potassiumphosphate buffer of pH 7.4 in microtiter plates at 37° C. for 5 min. Thereaction was started by adding NADPH (1.0 mM). After 0, 5, 10, 15, 20and 30 min, 65 μl aliquots were removed, and the reaction wasimmediately stopped and cooled with twice the amount of ethanol. Thesamples were frozen until analyzed. The remaining concentration ofundegraded test substance was determined by LC MSMS. The half-life (T½)was determined from the gradient of the signal of test substance/unittime plot, allowing to calculate the half-life of the test substance,assuming first order kinetics, from the decrease in the concentration ofthe compound with time. The microsomal clearance (mCl) was calculatedfrom mCl=ln 2/T½/(content of microsomal protein in mg/ml)×1000 (modifiedfrom references: Di, The Society for Biomolecular Screening, 2003,453-462; Obach, DMD, 1999 vol 27. N 11, 1350-1359).
